Word-Code Sentences
Whole sentences are coded word by word, with the codes in a mixed order; a word that two sentences share takes the code that their two codes share.
Why this matters
Twenty-six questions in the bank, twenty of them EASY. Eleven give two sentences and fifteen give three. The method is the common-letter method of the page before, one level up: shared words take shared codes, and what is left over pairs with what is left over.
Concept 1 of 2: Two sentences: the shared word takes the shared code
Definition
1. The codes are not in the order of the words. Never pair the first word with the first code. 2. A word found in both sentences takes the code found in both codes. 3. If two words are shared and two codes are shared, each shared word is one of the two codes, and nothing more can be said. Choose the 'either ... or' option. 4. A word in only one sentence is fixed only if it is the last word left once the shared words are placed. 5. Fast route: underline the shared word, ring the shared code, and read the answer straight off.

Concept 2 of 2: Three or more sentences: fix one word, then the next
Definition
1. A word in all the sentences takes the code in all the codes. Fix it first. 2. Compare sentences 1 and 2, then 1 and 3, then 2 and 3. Each pair's shared word takes its shared code, once codes already fixed are set aside. 3. A word left alone in a sentence after the others are fixed takes the code left over. 4. When the question asks for several words, decode only those; the options usually differ in one code. 5. If two words still share two codes, choose the option that is right whichever way they go. 6. Fast route: strike out any option holding a code you have already given to another word.
